Overview

This reference design is a half-bridge isolated gated driver used in driving power stages of UPS, inverters, server and telecom applications. This reference design is based on the UCC21520 reinforced insulated gate driver and is capable of driving MOSFETs and SiC-FETs. The design contains a built-in isolated push-pull auxiliary power supply for powering the output of the isolated gate driver. By bringing  together the isolated gate driver and isolated power supply in a compact board with a form factor (!~30 mm × 35 mm), this reference design provides a fully tested robust half-bridge driver solution capable of withstanding >100 kV/μs common-mode transient immunity (CMTI).

Features
  • Compact gate drive for driving power stages used in mid- and high-voltage power converters, single-phase and three-phase inverters
  • High-driving current (4-A source and 6-A sink) suits driving MOSFET/ SiC-FET with currents up to 100 A and operating frequencies up to 2 MHz, which reduces switching losses significantly
  • Supports 3250-VPK and 3000-VRMS basic isolation
  • Provides very High CMTI of > 100 kV/μs for robust operation in noisy high dv/dt environment
  • Integrated dead-time in gate driver improves reliability and avoids accidental shoot through of the power stage.
  • Built-in compact, high-efficient isolated supply to power the output side of the gate driver

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
